Cold War US spy satellite breaks apart in orbit, scattering debris — cause unknown

A Cold War-era American spy satellite has broken apart in low Earth orbit, scattering debris through one of the most crowded regions of space — and investigators do not know why.

U.S. Space Forces–Space confirmed that USA 32, catalogue number 19460, fragmented on September 13, 2026 at approximately 21:13 UTC, at an altitude of roughly 775 kilometres, The Zeal reported. The service said all tracked debris is being included in routine collision-risk screening, that no immediate threat to other spacecraft was identified, and that further analysis is continuing.

The spacecraft is widely identified as FARRAH III, a large signals-intelligence satellite built for the National Reconnaissance Office and described as resembling a “tuna can”. The secret FARRAH series was named after actress and model Farrah Fawcett. Launched on September 5, 1988 from Vandenberg Air Force Base aboard a converted Titan II missile, it spent 38 years circling the planet in a near-polar orbit, intercepting Soviet-era radar and radio emissions.

Swiss tracking company s2a systems recorded the aftermath on September 16, reporting that a large number of fragments had dispersed across a wide section of the satellite’s orbital track.

The cause remains unexplained. Analysts note an ageing spacecraft can retain stored energy in batteries and pressurised systems capable of violent failure — or the satellite could have been struck by debris or a micrometeoroid. German space-safety company OKAPI modelled both scenarios; its NASA-standard-breakup estimates suggest roughly 3,500 fragments larger than one centimetre, though those are modelling estimates, not observed pieces. The Space Force has attributed the event to no anti-satellite weapon or hostile action, and Gizmodo reported there is no evidence of a deliberate act.
